    摘要: Systems and methods for filtering dairy may filter milk with a wide-pore filter to produce a wide-pore retentate and a wide-pore permeate, wherein the wide-pore retentate may comprise casein and beta-lactoglobulin. The systems and methods may further ultra-filter the wide-pore permeate to produce an ultra-filtered retentate and an ultra-filtered permeate, wherein the ultra-filtered retentate comprises alpha-lactalbumin. The systems and methods may further nano-filter the ultra-filtered permeate to produce a nano-filtered retentate and a nano-filtered permeate, wherein the nano-filtered retentate comprises lactose. The systems and methods may further perform reverse osmosis (RO) on the nano-filtered permeate to produce a reverse osmosis retentate and a reverse osmosis permeate.

    摘要: A concentration method and equipment. The concentration method includes the step of performing reverse osmosis concentration processing on raw milk by using a reverse osmosis membrane. The reverse osmosis concentration processing includes low-pressure reverse osmosis membrane concentration processing and high-pressure reverse osmosis membrane concentration processing, wherein in the low-pressure reverse osmosis membrane concentration processing, reverse osmosis concentration processing is performed on feeding materials by using a first predetermined pressure, and in the high-pressure reverse osmosis membrane concentration processing, the reverse osmosis concentration processing is performed on the feeding materials by using a second predetermined pressure, the first predetermined pressure being lower than the second predetermined pressure. The concentration equipment includes a temporary storage unit, a homogenizing unit, and a particular concentration unit.

    摘要: The present invention relates to a method of producing an ideal whey protein concentrate. The whey protein concentrate has a pH in the range of 6.8-7.5 and 70-90% of the total proteins of the concentrate are whey proteins and 10-30% of the total proteins of the concentrate are caseins. The present invention relates also to an ideal whey protein concentrate and its uses in in reducing the total milk protein content and/or in increasing the whey protein content of a spoonable acidified milk product. In addition, the present invention relates to a method of producing a spoonable acidified milk product having high whey protein content but a reduced total milk protein content. The present invention relates also to a spoonable acidified milk product having high whey protein content but a reduced total milk protein content.

    摘要: A process for manufacturing a demineralized milk protein composition, including a step (ii) of electrodialysis of a milk protein composition on an electrodialyzer, the unit cells of which have three compartments, and configured to substitute at least one cation by at least one hydrogen ion H+ in the milk protein composition to obtain an at least partially demineralized and acidified milk protein composition; a step (iii) of electrodialysis of the milk protein composition obtained in step (ii) on an electrodialyzer, the unit cells of which have three compartments, and configured so as to substitute at least one anion by at least one hydroxyl ion OH− in the milk protein composition.
